PUMP.

Specification of Letters Patent.

Patented Mar. '7, 1911.

7 Application filed June 24, 1909. Serial No. 504,125.

T 0 all whom it may concern Be it known that I, TILLIAM VVrLLIsVILDER,'ZL citizen ofthe United States, residing at Savannah, in thecounty of Chatham and State of Georgia, have invented certain new anduseful Improvements in Pumps, of which the following is a specification.

This invention relates to pumps.

In taking hot or molten rosin from vats to barrels, the rosin isgenerally dipped out of the vat with clippers on long handles, anddelivered to the barrels, resulting in considerable waste from drippingsfrom the clippers and also because of the hot rosin splashing out of thevat in the dipping oper-' ation.

One object of the present invention is to provide a galvanized or otheriron pump adapted to-pump the rosin from the vat in its liquid state anddeliver it to the barrels without shifting the latter or the vat or thepump itself, thereby expediting the removal of the rosin from the vat tothe barrels and without unnecessary waste of the rosin.

Another ob ect of the invention resides in the provision of a pumpembodying such characteristics that it may efficiently pump pitch, tar,and other commodities that are heavy, including oils which areheavybodied, although the pump is particularly adapted for pumping rosinfrom vats into barrels, the pump having a sufliciently long reach fromthe bottom of the vat to the top of the rosin barrel, it standing on endso that the rosin will run by gravity from the spout into the barrel.

lVith the above and other objects in view, the present inventionconsists in the combination and arrangement of parts hereinafter morefully described, illustrated in the accompanying drawings andparticularly pointed out in the appended claims, it being understoodthat changes may be made in the form, proportion, size and minor detailswithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawings :-Figure 1 is a sectional view of a pump embodying myinvention. Fig. 2 is an inverted plan view of the lower end of the pump.Fig. 3 is a top plan view of the trough or gutter detached from thepump. Fig. 4; is a transverse sectional view of the gutter.

Referring now more particularly to the accompanying drawings, thereference character 1 indicates a pump barrel whose upper end is flaredat 2 and closed at 3 with the closure provided with a centralperforation for the guidance of the plunger roddnnounted preferablycentrally of the barrel and provided at its lower free end with theordinary valve mechanism 5, the plunger rod 4: being operated throughthe instrumentality of a lever 6 pivoted at 7 on the bracket 8 securedto the barrel 1 in any suitable manner. This lever 6 may be operated byhand or foot power or in any other suitable manner, as may be preferred.7

The lower end of the barrel 1 is flared outwardly, as at 9, with theextremity of the flared portions 9 crimped or otherwise formed toprovide the upper and lower annular shoulders 10 and 11, respectively,adapted to receive the annular or diskshaped valve seat 12 provided witha central opening 13 over which operates the valve 14 hinged in anysuitable manner at 15 to the valve seat 12.

The character 16 indicates a. strap-like foot piece which issubstantially U-shaped, with its leg portion 17 adapted to embrace thelower flared portion 9 of the barrel of the pump, the bight portion ofthe strap being in spaced relation to the lower end of the barrel sothat the rosin may enter the barrel without hindrance from the footpiece 16. This footpiece 16 is adapted to tightly embrace the lower endof the barrel to prevent accidental shifting or detach .ment thereof,and also to provide against an outward spreading of the lower flared end9 of the barrel to prevent accidental displacement of the valve seat 12.Additional means 24 may be employed to hold the foot piece l6againstdisplacement, if desired.

The barrel 1 is provided at its upper end I with a spout 18 which ispreferably cylindrical in cross section, and through which rosin drawnup through the barrel is discharged. I

The character 19 indicates a trough or gutter which is substantiallysemicircular in cross section throughout practically its entire length,with metallic or other strips 20 embracing the longitudinal edges of thegutter for the support of handles 21, whereby the gutter may be easilyhandled for transportation from one place to another. The inner end ofthe gutter is preferably cylindrical in cross section, therebyproviding,

what may be termed an apron 22 adapted to to.

fit over the spout l8 and by which the gutter is loosely supported uponthe spout 18. It will be seen that the edges of the gutter are curledfor the purpose of strengthening the edges thereof, as indicated at 23in Fig. 4:.

The pump barrel is formed preferably of galvanized iron, and the iron ofthe pump is all riveted, so that the heat of the hot or molten rosinwill not affect it. The rosin sticks and gums up the pump after beingused each time, but can be easily cracked off or, after being used onone vat of rosin, the rosin that may stick or cling to the pump in theremoval of the rosin from said vat will be quickly melted when the pumpis inserted in another vat full of hot rosin and the pump operated,thereby maintaining the pump in satisfactory operable condition. Therosin that may stick to the gutter may be easily chipped or cracked off,as will be obvious, but in the event that it is not chipped or brokenoff in any other suitable manner, the rosin that may cling to it, as

the result of operation, will be easily and quickly melted when the pumpis again put into commission.

In the accompanying drawings, the pump barrel is shown as being disposedupon an incline. In this position it will be understood that the lowerend of the barrel is positioned in a vat of hot rosin (not shown), withthe outer end of the gutter 19 disposed upon the upper edge of a barrel.By operating the lever 6, the plunger is manipulated to open and closethe valves 5 and 14, respectively, to lift the hot rosin from the vatupwardly through the barrel and out through the spout 18 into the gutter19 to the rosin receiving barrel (not shown), all without waste of rosinand greatly expediting the filling of the barrels, as compared with theold method hereinbefore referred It will be understood, however, thatthe pump need not be inclined, as shown, but that the same may bedisposed vertically without departing from the spirit of the inventionor interfering with an efficient operation of the device. However, whenthe pump and its aggroupments are positioned as shown in the drawings,there is a greater gravitation provided for the flow of rosin to thebarrel, especially is there a greater gravitation in the gutter 19.

IV hat is claimed is l. A pump comprising a barrel composed of sheetmetal and having its lower end flared with the outer end of the flaredportion crimped to provide inwardly directed, spaced, annular shoulders,an annular valve seat positioned between said shoulders, a valve hingedon said seat, a foot piece secured to the flared portion of the barrel,a plunger operable in the barrel, a bracket se cured to the barrel withits outer end ex tending beyond the upper end of the barrel, and a leverfulcrumed on the bracket and having operable connection with the plungerto operate the latter.

2. A pump comprising a barrel having its lower end flared outwardly,with its outwardly flared portion having its lower edge formed toprovide a shoulder, a valve seat positioned between said shoulder andthe inner end of the flared portion of the barrel, a valve hinged onsaid seat, a foot piece secured to the flared portion of the barrel, aspout connecting with the barrel, a plunger operable in the barrel, andmeans for operating the plunger.

In testimony whereof I affix my signature in presence of two witnesses.
